Be it known that I, CHARLES A. KOCH, a citizen ofthe United States, residing at Austin, in the county of Travis and State of Texas, have invented a new and useful Hat Pin-Point Protector, of which the following is a specification.

The device forming the subject matter of this application is adapted to be used for protecting the point of a hat pin, and the invention aims to improve the operative connection between the complemental memhere which shield and grip the point of the It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without de-' parting from the spirit of the invention.

In the accompanying drawings Figure 1 shows in longitudinal section, a hat pin point protector constructed in accordance with the present invention, parts appearing in elevation;

Fig. 2 is a cross section on the line 22 of Fig. 1;

Fig. 3 is a cross section on the line 3-3 of Fig. 1; and

Fig. 4 is a side elevation showing the protector forming the subject matter of this application, mounted on the end of a hat pin.

The structure-formin the subject matter of this application preferably is made out of steel or other hard material and includes a body B provided at one end with a flared guiding mouth 1. In the body B to the rear of the guiding mouth 1 there is fashioned a flared bore 25, the bore 25 and the mouth 1 tapering in opposite directions, and the small ends of the mouth 1 and the bore 25 being in communication, as indicated at 18. In the body B to the rear of the flared bore 25, a cylindrical bore 13 is formed, the same being internally screw threaded as shown at 10. The cylindrical bore 13 forms in the body B, at the rear end thereof, a relatively Specification of Letters Patent. Patented A131, .9, 1918. Application filed-February 2,191,65- Seria1No.75,864. i

thin wall,'- the extremity of which is turned inwardl ioward the axis of the body B to form a retaining flange 26.'-' j The invention comprises a button including a terminal head D and a reduced neck a. The neck a extends within the cylindrical bore '13 and the flared bore 25 and is beveled as shown at 38 to cooperate .with the wall of the flared bore 25. The forward or inner end of the neck a is supplied with longitudinal slots 2, 3 and a defining compressible pin-gripping arms 5, 6 and 7. In the head D and the neck a is formed an axial pin seat 8 which is extended as shown at 28, onto the inner edges of the arms 5, 6 and 7. Intermediate its ends, the neck a of the but- ,ton is provided with a screw threaded portion 9, which is of greater diameter than the neck a itself, thereby to form a shoulder 27. The screw threaded portion 9 of the neck a cooperates with the threads 10 in the cylindrical bore 13 and the shoulder 27 is adapted to cooperate with the retaining flange 26.

In practical operation the button AD'is rotated readily by means of the head D, since this head is of greater diameter than the body B, and since the head D and the body B are milled as shown at 39, so that one of the parts may be held while the other is being rotated. The button may be backed partially out of the body B, when the button 7 is rotated, and the outer beveled edges 38 of 'nection it is to be observed that the shoulder 27 is adapted to coiiperate with the flange 26, to prevent a complete separation between the body B and the button. The numeral C indicates one end of a hat pin, which may be guided by the mouth 1 into the pin seat 8. Then. if the button be rotated, the cooperating threaded portions 10 and 9 will advance the button, causin the beveled parts 38 of the arms 5, 6 and to cooperate with the flared bore 25, the arms gripping the pin C in a manner which will be obvious to those skilled in the art.

The device forming the subject matter of this application provides a means whereby the point of a hat pin may be shielded, the protecting structure being held securely on the end of the hat pin, and a means being provided whereby an accidental separation of the parts of the protecting structure will be avoided.

Having thus described the invention, what is claimed is A hat pin point protector comprising a tubular body provided adjacent one end with a tapered bore and providedat its other end with a projectin flange; and a button threaded into the body andprovided at one end withgrippin'g jaws cooperating with the. tapered bore, the other end of the button being exposed with respect tothe body, to permit a rotation of the button, the

copies of this patent maybe obtained for buttonbeing suppliedintermediate its ends 15 ton is retracted, to prevent a separation of 20 the body and the button. V v

Intestimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses;
